11 Claims. (Cl. 229-55) My invention relative to new and useful improvements in a container and closure cap therefor, and more particularly to a closure cap for a readily destructible container formed of relatively thin and flexible material such as paper and primarily intended for but a single use, and in so far as there is commcn'subject matter the present application is a continuation in part of my application filed November 27, 1931, Serial No. 577,605.

. The principal object of the invention resides in'the provision of a closure cap adapted to be received upon and enclose the normally open end i of the container, the cap including a top portion and a depending flange or skirt, the flange'being readily flexible permitting a sumcient expansion to permit the application of the cap to the container, and the top portion of the cap and the flange or skirt being formed and related to provide a groove or recess to receive a bead or flange formed around the edge of the normally open end of the container.

A further object of my invention resides in forming the flange or skirt of the cap to provide 5 reinforcements to maintain the flange or skirt in its normal formation and while permitting flexing thereof in applying the cap to the container adding s'uflicient strength to prevent such distortion as would tend to provide a loose fit between the cap and containeu.

Another object ofmy invention consists in forming the flange or skirt of the cap with crimped or overlapped portions, forming the reinforcements, said crimped oroverlapped portions extending vertically of the flange or skirt and to a point where the groove or recess in the cap is formed, these crimped 0r overlappedmortions adding strength at the point where the groove or recess is formed to receive the bead orflange on the upper edge of the container.

A still further object of the invention resides in the provision of a blank from which the cap is formed, said blank being formed around its marginal edge with inwardly extending scores or indentations whereby when the flange orskirt is turned from the blank the folds or crimps will take place at the scores or indentations to provide the .crimped or overlapped portions which, as previously described, extend vertically of the flange or skirt to provide circumferentially spaced reinforcements.- As a further object of the invention I provide a cap, of paperor similar material, which may be readily snapped over a container formed of paper or the like, saidcap the normally open end of which will appear as the description proceeds,

invention consists in the novel details of coristruction, and arrangement of parts, described in the following specification and illustrated in the accompanying drawings, and while I have, illustrated and described the preferred embodiments of the invention, as they now appear to me, it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawings:-

Fig. lis a transverse vertical section through a container and a closure cap positioned thereon.

Fig. 2 is a plan of the blank from which the closure cap is formed.

Fig. 3 is an edge view of the closure cap.

Fig. 4 is a fragmental, enlarged, view. looking into the underside. of the cap towards the bead 'or skirt portion thereof; and

Fig. 5 is a fragmental transverse vertical section through the upper edge portion of the container and the closure cap positioned thereon.

'In the drawings it indicates generally the container formed of relatively thin paper or similar material and b indicates the closure cap therefor, said closure cap being formedof paper or similar material and adapted to be engaged over the normally open end portion of the container. The container includes the tapered body portion l, the bottom 2, and the outwardly directed head or flange 3, the bead or flange being formed around the normally open mouth portion of the container while the lower edge of the body I is folded inwardly as shown at 4 beneath the bot- Y tom 2.

'I'heclosure cap I) includes the top portion 5 and outwardly flared flange or skirt portion 6 connected by the circumferentially extending ward flare oi the flange or skirt 6 forms an inwardly directed circumferentially extending rib l0 forming a restricted passageat. the point where the bead l connects with the skirt 8, said inwardly directed rib It being of less circumference than The closure cap is formed from a blank of the.

formation shown more particularly in Fig. 2 of the drawings, the blank being circular in form and provided around its marginal edge with circumferentially spaced inwardly extending scores or indentations ll. As the flange or skirt 6 is turned folds or crimps' will take place at the scores or indentations I I to provide circumferentially spaced overlapped portions such as are shown at l2 moreparticularly in Fig. 4 of the drawings and, as shown, these overlapped portions are not of uniform character but take up the surplus material in'the'flange or skirt 6, it being understood that when the flange or skirt is turned there will necessarily be some surplus material due to the reduction in diameter. The overlapped portions I"! will extend vertically of the .flange or skirt 6 and are of such a height as to-extend from the lower edge of the flange or skirt tothe upper surface, or approximately to the upper surface, of the bead 1 thereby reinforcing the flange or skirt 6 as well as the bead 1.

0 The overlapped portions I! tend to hold the.

. flange or skirt 6 and bead 1 in their normal formation, but will permit suflicient flexing thereof to allow the closure cap to be positioned overthe normally open, endof the container.

From the above detailed description it is thought that the construction will be clearly understood. It will be seen that I have provided a closure cap, formed of paper or'similar material, which is adapted to be placed over and enclose 40 the normally open end of. a container which is also formed of paper or similar material and by reinforcing the skirt or flange 6 of the closure cap as well as the bead 1 the cap will snugly engage the container and such flexing as is neces- 5 sary in applying thecap to the container will not distort theflange or skirt, and the bead 1 as to prevent snug engagement of the cap with the container. The overlapped portions I2 further have a tendency to return the flexed flange or skirt to 50 its normal position after application to the container. The outward flare at the bottom of the flange or skirt 6,. will guide the closure cap over the normally open end of the container and as the bead 3 of the container engages the inwardly 55 directed rib In it will flex the skirt or flange s outwardly to permit the bead 3 to pass intothe groove 8 formed interiorly of the flange or skirt and the bead 3 of the container will be positioned, as more particularly in Figs. 1 and 5 of the drawings between the inclined portion 9 of the cap and the skirt or flange 6. The closure capes well as the container being formed of flexible material such as paper permits sufllcient flexing between the parts to permit the application of the cap over the end of the container but at the same time permitting close engagement of the cap with the container. It will be understood that the overlapped portions l2 will be 70 pressed tightly together and Fig. 4 of the drawings shows a greatly enlarged section. Although pressedrelatively flat nevertheless the overlapped portions will provide slight vertical projections or ribs both interiorly and exteriorly of the flange 75 or skirt 6', the interior projections or ribs being engaged by the bead 3 of the container as the cap is applied.

A closure cap such as is described may be easily applied to the container and at the same time protects the lip of the normally open end of the container against the accumulation of impurities thereby having advantages over the well-known form of disc closure inserted into the normally open mouth of a container.
